My cookie

Yesterday Zaleha called me asking us to come to her house and showing off her two cookies which she has completed. Feeling excited and yet I did not start any , so today I intended to prepare at least two cookies for myself. Yesterday the three of us did our shopping again buying stuff for making cakes. Finally today , I completed one cookie called as mama carries which I get it from my friend in Miri.
